?? 7 #所以它們能把輸出提供給xargs并處理
?? 8 #例如： broken-link.sh /somedir /someotherdir|xargs rm

? 10 #下面是更好的發現死符號鏈接的辦法:
? 11 #
? 12 #find "somedir" -type l -print0|\
? 13 #xargs -r0 file|\
? 14 #grep "broken symbolic"|
? 15 #sed -e 's/^\|: *broken symbolic.*$/"/g'
? 16 #
? 17 #但這不是純bash腳本，下面的則是.
? 18 #注意: 謹防在/proc文件系統和死循環鏈接中使用!
